F&M Oil Filter Installation position?

[blueldr]

In making a 1" square socket for an oil filter wrench, if you use a 1/2" eight point square socket, bolt end for the drive end, you will have a wrench that can take a new bite at 45 degrees instead of 90 degrees.

Had an f&M spin on oil filter adapter installed at the last annual by my A&P. He installed it at about the 8:00 o'clock position looking forward from the back of the engine. Problem is that the adapter is loosening from gravity, engine movement, etc. Ideally, I would like for it to hang straight down at the 6:00 o'clock position but the engine mount cross brace gets in the way (C145 Engine). I am thinking of moving it to the 5:00-5:30 position so that the force of gravity pulling down on the heavy end will exert a "tightening" force rather than a "loosening" force as was the case when it was at 8:00 o'clock. The only question is, how much clearance do I need between the filter and the surrounding engine mount and other fixtures? I can get somewhere between a 1/4 inch and a 1/2 inch when located at about the 5:00 o'clock position but I don't get the full 1/2 inch that F&M recommends. At the 5:00 o'clock position, the adapter body is close to the engine mount cross brace and the bottom end of the filter is close to the fuel line fitting on the gascolator. How much clearance do I realistically need?


Anyone care to share your thoughts?

Thanks!

Jim...if you read the FM installation instructions (which are included in the kit and the STC) you will see that 1/2" of clearance must be provided. If you can obtain that in the 5-5:30 position (as you indicate you prefer anyway)...then do that.
